What Kling & Freitag does

Kling & Freitag GmbH is a privately held, family-run German manufacturer of professional loudspeaker systems and system amplifiers, headquartered in Hannover since its founding in 1991. The company operates two principal product divisions: pro.RENTAL, covering touring and portable loudspeakers (including the SEQUENZA line array family, VIDA, GRAVIS, PASSIO, SONA, and PLA), and pro.INSTALL, covering fixed-installation amplifiers and processors (D Series, PLM+ Series, IPX Series, IX Series, and TGX Series SystemAmps, plus the K&F SCALA immersive audio processor). Its technical differentiators are the patent-pending TrueShape® horn architecture and AutoLock® rigging system, complemented by deep integration with Lake® processor technology, Dante/AES67 networking, and proprietary system software (Lake Controller, SONICUE, CON:SEQUENZA+).

Kling & Freitag sells exclusively through B2B channels: a direct sales team and regional managers in Germany, a network of 25+ authorized System Partners in Germany, and 40+ international distributors covering Europe, Asia, the Americas, Africa, and the Middle East. Pricing is quote-based and not publicly disclosed, with delivery terms ex works Hannover. Revenue is generated through hardware sales of loudspeakers and amplifiers, software licenses (CON:SEQUENZA+), and professional services for repair and maintenance. Customer logos span high-prestige venues and events, including the Bregenzer Festspiele, Elbphilharmonie Hamburg, G20 and BRICS summits, multiple Chinese opera houses, and German sports stadiums. The company is led by Managing Directors Jürgen Freitag (International Sales) and Jonathan Freitag (Co-CEO), with no disclosed external investment, parent company, or subsidiary structure.
